Effect of Alcohol Washing and pH Value of Leaching Solution on Positive and Negative Charges in Ferruginous Soils

Abstract

ARISING from an investigation of the variation in positive and negative charge with pH in a number of ferruginous tropical soils1, it appeared that the use of alcohol washings in the determination of cation exchange capacity (CEC) on such soils might lead to serious errors.
